Participants are signed up from 22 states. The event, which features a half-marathon, 5K, and kids’ 1-mile fun run, kicks off at 7 a.m. at Davis Park, 318 S. Wyman St.

Finalists Bobby Saleem and Tanya Winfield from the 15th season of “The Biggest Loser” also will participate in the event.

Last year, more than 2,500 people participated in the event, which brought an estimated 6,000 visitors to downtown Rockford, according to organizers. One dollar from each registration this year will be donated to the Rock River Valley Pantry.

The event is aimed at helping people reach their fitness goals, whether they’re avid runners or beginners. Registration for the various events range in cost from $15 to $85.
